Abstract

The invention provides an ultraviolet-cured anti-dazzle hard film and application thereof. The ultraviolet-cured anti-dazzle hard film comprises a transparent supporter and an anti-dazzle hard film coating coated on at least one surface of the transparent supporter. A formula for the coating comprises, by weight, 5 to 90 parts of an ultraviolet-cured resin, 5 to 90 parts of a solvent, 1 to 10 parts of a photoinitiator, 0 to 80 parts of a reactive diluents, 1 to 40 parts of an anti-dazzle particle and 0 to 6 parts of an auxiliary agent. Compared with the prior art, the invention has the following advantages: the ultraviolet-cured resin contains a certain amount of an organic silicon resin, which enables the antifouling property of the surface of the anti-dazzle hard film to be improved; and the selected organic particle has good compatibility with the ultraviolet-cured resin, so transmission loss of light is reduced, which enables clarity of displaying by the anti-dazzle hard film to be improved. The ultraviolet-cured anti-dazzle hard film has good anti-dazzling performance, a good antifouling effect, high hardness, good scratch resistance, excellent flexibility and high resolution.

Description

technical field [0001] The invention relates to an ultraviolet light curing antiglare hard coating film used for protecting various displays and touch screens. Background technique [0002] In recent years, various new flat panel display (LCD, OLED, EL, PDP) technologies and products have developed rapidly. The flat panel display industry has become an important part of the information industry. The flat panel display industry and market are growing rapidly worldwide. The external surface of various flat-panel displays reflects the surrounding strong light or the strong light generated inside enters the human eye, which is likely to cause glare and blur, and the screen content cannot be clearly displayed. This phenomenon is called glare. In order to solve such problems, it is necessary to attach a hard coating film that has been roughened and anti-glare to the surface of various displays to reduce glare and improve the clarity of image quality. The usual method is to form a...
